Apple Home can show real-time power use and historical energy data for compatible Matter accessories, according to Matter Alpha’s setup guide. The report also describes Grid Forecast and utility-account connections, which have separate availability limits; Apple has not confirmed those details in the supplied material.
Apple Home can display live power use and historical energy records for compatible Matter accessories, according to a setup guide published by Matter Alpha. The report explains where users can find the data and how to enable Grid Forecast, while noting that device compatibility and some broader energy features are limited.
For live readings, the guide says users need a Matter accessory with energy-monitoring capability that has been added to Apple Home. In the Home app, tap Energy or Grid Forecast, then tap Power. The resulting Power screen lists compatible devices; when one is drawing power, its current consumption appears beneath its name. The Energy screen also displays a live total for the listed devices.
To view past usage, open Energy or Grid Forecast and wait for Usages to appear below the Grid Forecast timeline. Tap Usages, open the device menu and select an accessory. The guide says the charts show energy totals and averages for day, week, month, six-month and year periods. Cleaner and Less Clean controls can highlight when usage occurred during cleaner or less-clean grid periods, based on location.
The report names the Inovelli White Series Smart Dimmer Switch, Aqara Thermostat Hub W200 and Eve Energy In-Wall Outlet as examples it has seen working with Apple Home’s energy display. These examples do not establish that every model, firmware version or regional setup is supported. The supplied guide does not provide a full compatibility list or specify the measurement units and update interval for every accessory.
What Home Energy Data Can Show
Device-level readings can help users see which connected accessories draw power and how that usage changes over time. That may make it easier to identify consumption patterns, but the display alone does not establish how much money a household will save. Actual savings depend on the device, electricity rates, household behavior and, where relevant, the utility’s billing plan.
Grid Forecast adds a separate timing view, indicating when local electricity is expected to be cleaner or less clean, the guide says. Users on time-of-use rates may be able to compare usage timing with their plan, while others may use the information to shift some consumption. The guide describes this as an aid, not a guarantee of lower bills or emissions.
Access also varies by feature. The report says Grid Forecast is available to homes in the contiguous United States, while utility-account integration is limited to two providers named in the article. The live and historical device readings, by contrast, depend on having compatible monitoring accessories.

Three Routes to Energy Information
The Matter Alpha report describes three related but distinct sources of information in Apple Home: readings from compatible smart accessories, Grid Forecast for local grid conditions, and whole-home consumption data supplied through an electric utility account. These should not be treated as interchangeable. Access to accessory readings does not mean a utility connection is available, and a Grid Forecast timeline does not itself measure every appliance in a home.
According to the guide, Grid Forecast requires Location Services for both the Home app and Home Service on iOS, iPadOS or macOS. To turn it on, open Home, tap the more-options button, choose Home Settings, then Energy, and enable Show Grid Forecast. A Grid Forecast button should then appear in the app. The guide also says users can tap the bell icon and choose Notify Me for clean-energy notifications, and can add a widget on iOS or macOS.
For whole-home readings, the guide says eligible users can open Home Settings, choose Energy, tap Connect Account and follow the prompts to connect a utility account. It identifies Pacific Gas and Electric and Southern California Edison as the providers supported at the time of its report. Once connected, the app can show utility-supplied consumption data covering more than the Matter accessories visible individually in the Home app.
““When a device is actively drawing power, real-time energy consumption data will appear underneath its name.””

Compatibility and Regional Limits
The supplied source is a third-party setup guide, not an Apple announcement or complete technical specification. It says the feature was introduced in iOS 27, but the material provided does not independently confirm the operating-system release details, the availability of each feature across Apple platforms, or whether interface labels vary by software version.
The report does not list every compatible Matter accessory, explain whether all supported devices report energy in the same way, or state how frequently readings update. It also gives no date for its utility-provider coverage. Its claim that Grid Forecast is available across the contiguous United States excludes Alaska and Hawaii, but the source does not clarify whether availability depends on additional local or account conditions. The listed utility integration is limited to PG&E and Southern California Edison in the report; broader provider support is not established by the supplied material.
Check Support Before Connecting
Users interested in the feature can check whether their specific accessory supports energy monitoring and appears in Apple Home before relying on its readings. They can then review the Power screen for live use and Usages for historical charts. To try Grid Forecast, they will need to enable the feature in Home Settings and allow the required Location Services settings, according to Matter Alpha’s instructions.
Those seeking whole-home data can check whether their electric provider is supported and connect an account through Home Settings if the option is available. Further details that would clarify the feature include an official Apple compatibility list, current regional availability, supported utility providers and the precise data refresh and measurement behavior for different accessories.
Key Questions
What do I need to see energy use for a Matter device?
You need a Matter accessory with energy-monitoring capability added to Apple Home. The report says supported accessories appear in the app’s Power screen; it does not provide a complete list of compatible products.
Where are live and historical readings in Apple Home?
For live readings, tap Energy or Grid Forecast, then Power. For historical charts, open Energy or Grid Forecast, wait for Usages to appear, tap it and select a device from the menu.
How do I enable Grid Forecast?
In the Home app, open the more-options menu, choose Home Settings, then Energy, and turn on Show Grid Forecast. The guide says Location Services must be enabled for the Home app and Home Service.
Can Apple Home show my whole-home electricity use?
The guide says users can connect a supported utility account under Home Settings and Energy. It names Pacific Gas and Electric and Southern California Edison as supported providers, but does not establish availability with other utilities.
Does energy monitoring guarantee lower bills?
No. The app can display consumption and grid timing, but those readings do not guarantee savings. Any bill reduction depends on usage changes, electricity rates and the household’s utility plan.
